Discuss the impact of LUNG DISEASE (excluding that caused by asbestos) in the workplace - Essay Example Though the air we inhale contains mostly oxygen and nitrogen, it also has things that can damage the lungs. Bacteria, viruses, tobacco smoke, car exhaust, and other pollutants ate present abundantly in air. People with lung disease have difficulty in normal breathing. These breathing problems may prevent the body from getting enough oxygen. It is not a surprise that people with lung disease find it difficult to work as normal people, walk and swim, run or does any other work as normal person. This paper discusses the impact of lung disease in the workplace. By understanding some basics about chronic obstructive pulmonary disease (COPD) and its symptoms, it is possible to analyses its impact on the every day work or its impact on the workplace. COPD is a condition in which the air passages are damaged, leading to shortness of breath and increased coughing. Emphysema and chronic bronchitis are forms of COPD. In the case of emphysema, the lung’s air sacs loose their elasticity. As a result of this the exchange of oxygen to carbon dioxide becomes very difficult. Additionally, the air sacs are often damaged, leaving fewer of them to do the work. These factors result in the shortness of breath and make it very difficult for a person to perform normal work. Chronic bronchitis is another form of COPD. In this case the small airways within the lungs become inflamed and harden over time. Besides the cilia which are the small protective hairs that clear mucus also losses its effectiveness and the mucus glands enlarge. The narrowed airways together with increased mucus cause congestion and coughing and make it more difficult to breathe. There are many who have both emphysema as well as chronic bronchitis. Most people with these diseases find breathing trouble to be the most problematic among the symptoms (Wilkinson, 2002). According to studies it is said that COPD is the only primary cause of death that is ever-increasing in occurrence. Even though it is a well known

The author mentions ways for reducing the cost of construction of nuclear plants to make it affordable in the society. The main topic of the article is improving efficiency in nuclear power plants. It discusses innovative techniques and safety measures that can ensure nuclear energy plants maintain efficiency. The author supports nuclear power. He chooses this position because he believes that there are innovative measures that can ensure safety in nuclear power plants. Their arguments are based on latest research on technology that is useful in nuclear power plants. The source is credible because it discusses incremental innovations in the digital world, and enhancements of safety margins in an existing power plant. I have chosen this source because it provides a solution for risks involved in nuclear power plants. The dangers and effects of nuclear plants remain the greatest challenge that opponents of nuclear energy discuss. The main topic of the article is making nuclear energy sustainable. The paper analyzes and reviews the challenges that nuclear power must get through before the society accepts it as a sustainable energy source. Pearce is obviously against nuclear power as an energy source because it is not sustainable. He chose this position because of its associated environmental burdens, specifically greenhouse gas emissions and nuclear and radioactive waste disposal. In addition, he cites nuclear insecurity as a danger of nuclear energy,
